Lean Horse

Custer, SD 100 Miler Relay, 100 Miler, 50 Miler, 30 Miler, 20 Miler

This Event Took Place Fri. Aug 17, 2018


The Lean Horse 100 is considered to be one of the best first time ultra’s in the country because of the great running surface and gentle elevation changes.

There are many things that have changed at the Lean Horse 100 over the years. But one thing that does not change is the "small town" feel of the race. The crew at Lean Horse wants to make sure that your ultra is the race that you will never forget.

For more than ten years, the Lean Horse 100 has inspired runners of all abilities and from all walks of life, from all over the country and world to come to South Dakota to test themselves over the 20 Mile, 30 Mile, 50 mile, 100 mile, and 5 Person Relay distances.

Lean Horse 100 Relay Information

The Lean Horse 100 wants to bring you into the sport of ultra running with the support of friends and family in “bite size” chunks of running.  We are offering runners the option to participate in relay teams of 5 people. If this is your first time venturing in to the distance relays, then you’re in for a real treat. Imagine you and a group of your closest friends (or newest friends) running through the beautiful Black Hills of South Dakota on the George Mickelson Trail. Traveling through the scenic Black Hills in a van with other people, running on one of the most scenic trails around and developing memories and stories that you will share for a life-time. Then we have no doubt that this will be an experience you’ll never forget. Please go to to learn more.
